Invisible Cities - Architecture silhouettes

Since I did not want my city to consist of purely generic skyscrapers and buildings, I tried experimenting with different shapes for how the tops of large buildings could look, just to keep the city having it's own "flavour". Though keep in mind the city I'm working on is Tamara, so I want to keep the architecture fairly minimal, nothing too fancy. Reason being that I want more focus to be placed on all the signs that will be covering the buildings.

Worked on this Monday, forgot to upload it then.
